Description

Technical Field

[0001] The utility model relates to the technical field of aluminum extrusion dies, and particularly relates to a quick disassembly device for a small die. Background Art

[0002] During the aluminum profile extrusion production process, after the aluminum profile extrusion die is removed, a certain amount of waste aluminum often remains. This waste aluminum will block the holes in the die, resulting in the inability to smoothly separate the die. This problem not only affects the repair and reuse of the die, but may also extend the production cycle and increase production costs. In order to separate the aluminum profile extrusion die, it is necessary to first perform a boiling die treatment on the die, that is, lift the die into an alkali tank filled with sodium hydroxide solution to clean the waste aluminum blocked in the die holes, and then manually separate the die.

[0003] However, the commonly used method of manually separating the die now is to use a self-made crowbar and a hammer to strike the gap of the die to manually separate the upper and lower dies. This method is time-consuming and laborious, with low efficiency when separating the extrusion die. It may also cause damage to the die surface, forming scratches, dents or other physical damages, thereby affecting the accuracy and service life of the die. In addition, there may also be a risk of accidental injury. For example, the hammer may slip or the crowbar may fall off, which may cause injury to the operator. Therefore, in view of the above problems, we have proposed a quick disassembly device for a small die. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a quick disassembly device for a small die to solve the problems of die damage, low efficiency and possible accidental risks caused by the existing manual die separation method.

[0005] To solve the above technical problems, the utility model provides a quick disassembly device for a small die, including a support member; an impact member, which is used to enhance the impact effect and concentrate energy to disassemble the upper and lower dies; and a die.

[0006] The support member includes an outer support seat, an inner support seat disposed on one side of the outer support seat, and a connecting member disposed between the outer support seat and the inner support seat;

[0007] The outer support seat is in the shape of a semi-cylindrical ring, and the inner support seat is in the shape of a 1 / 4 cylindrical ring;

[0008] The inner support seat is disposed inside the outer support seat and can slide out of the outer support seat to form a 3 / 4 cylindrical ring.

[0009] Preferably, the outer support seat includes first slide rails disposed on its top and bottom surfaces, and a plurality of first ball grooves disposed between the first slide rails.

[0010] Preferably, the ball groove includes a limiting block provided at its outlet.

[0011] Preferably, the inner support seat includes second slide rails provided on its top and bottom surfaces, multiple second ball grooves provided between the second slide rails, and a handle;

[0012] The first slide rail and the second slide rail are complementary to each other, so that the inner support seat can slide out of the outer support seat along the slide rail.

[0013] Preferably, the second ball groove includes an anti-slip protrusion provided at one end thereof.

[0014] Preferably, there are bayonets for supporting the upper die at the top of the outer support seat and the inner support seat.

[0015] Preferably, the connecting member is a plurality of rolling steel balls, and the rolling steel balls are arranged in the first ball groove.

[0016] Preferably, the impact member includes a force-receiving area and a plurality of force-transmitting legs fixed to one side of the force-receiving area.

[0017] Preferably, the mold includes an upper mold, a lower mold, and a plurality of mold grooves provided on the mold.

[0018] Preferably, the force-transmitting legs can be correspondingly inserted into the mold grooves.

[0019] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0020] 1. The rapid disassembly device for a small mold of the present utility model enables the external impact force to be evenly and centrally distributed to the lower mold of the mold through the design of the support seat bayonet and the force-transmitting legs, thereby reducing damage to the surface of the mold and reducing the risk of mold wear and deformation. When the lower mold falls, it will directly fall into the cavity formed by the two support seats. In the conventional method of using a crowbar and a hammer for disassembly, the mold is very likely to fly off at the moment of mold separation, causing damage to the surrounding environment and even personal safety. In summary, this device greatly improves the stability, reliability, and safety of the disassembly process;

[0021] 2. The rapid disassembly device for a small mold of the present utility model can quickly wrap and fix the mold through the design of the ball sliding mechanism. The frictional resistance during sliding is significantly reduced, greatly reducing the time and labor consumed in the traditional method, and improving the work efficiency.

[0030] The present utility model provides a quick disassembly device for a small mold. Please refer to Figures 1 to 3 , which includes a support member 1; an impact member 2, which is used to enhance the impact effect and concentrate energy to disassemble the upper and lower molds; a mold 3; the support member 1 includes an outer support seat 101, an inner support seat 102 disposed on one side of the outer support seat 101, and a connecting member 103 disposed between the outer support seat 101 and the inner support seat 102; the outer support seat 101 is in a semi-cylindrical shape, and the inner support seat 102 is in a 1 / 4 cylindrical shape; the inner support seat 102 is disposed inside the outer support seat 101 and can slide out of the outer support seat 101 to form a 3 / 4 cylindrical shape.

[0031] The outer support seat 101 includes first slide rails 101a disposed on its top and bottom surfaces, and multiple first ball grooves 101b disposed between the first slide rails 101a; the ball groove 101b includes a limit block 101b-1 disposed at its outlet; the inner support seat 102 includes second slide rails 102a disposed on its top and bottom surfaces, multiple second ball grooves 102b disposed between the second slide rails 102a, and a handle 103; the first slide rails 101a and the second slide rails 102a are complementary to each other, so that the inner support seat 102 can slide out of the outer support seat 101 along the slide rails; the second ball groove 102b includes an anti-slip protrusion 102b-1 disposed at one end thereof.

[0032] The outer support seat 101 and the inner support seat 102 have a bayonet 104 at the top for supporting the upper mold; the connecting member 103 is a plurality of rolling steel balls, and the rolling steel balls are disposed in the first ball groove 101b; the impact member 2 includes a force-receiving area 201 and a plurality of force-transmitting legs 202 fixed to one side of the force-receiving area 201; the mold 3 includes an upper mold 301, a lower mold 302, and a plurality of mold grooves 303 disposed on the mold 3; the force-transmitting legs 202 can be correspondingly inserted into the mold grooves 303.

[0033] It should be noted that since the support member 1 needs to bear the impact force generated by the impact member 2 during mold disassembly, its material needs to be selected as a high-strength rigid material, especially the bayonet 104 part. Specifically, it can be a kind of load-bearing carbon steel with high strength and strong wear resistance to ensure its service life.

[0034] Preferably, the upper and lower top surfaces and the bottom surface of the outer support seat 101 are all provided with first slide rails 101a, and a first ball groove 101b is provided between the first slide rails 101a. Similarly, the upper and lower top surfaces and the bottom surface of the inner support seat 102 are all provided with second slide rails 102a, and a second ball groove 102b is provided between the second slide rails 102a. The structures of the first slide rail 101a and the second slide rail 102a are complementary to each other, and the first ball groove 101b and the second ball groove 102b jointly form a ball slideway in which a plurality of rolling steel balls roll, so as to reduce the friction generated between the inner support seat 102 and various parts of the outer support seat 101 when the inner support seat 102 slides out, play the role of a rolling bearing, thereby reducing energy consumption and improving the efficiency of pulling out the inner support seat 102 through the handle 102c.

[0035] Preferably, a limit block 101b-1 is fixedly installed at the outlet of the ball groove 101b on the outer support seat 101 to prevent the balls from rolling out of the ball groove 101b. Similarly, an anti-slip protrusion 102b-1 is fixedly installed at the starting end of the second ball groove 102b of the inner support seat 102, which can effectively prevent the balls from sliding out of the groove due to vibration, inclination or improper operation during work, ensuring the stability and safety of the system.

[0036] Preferably, the working principle of this device is to use the bayonet 104 to engage the gap between the upper and lower molds of the mold 3, and then use a hammer to strike the lower mold through the impact member 2 from the outside to make it fall off. The structure of the bayonet 104 is as Figure 2 shown, and its diameter is slightly smaller than the diameter of the mold 3.

[0037] Preferably, the shapes and numbers of the mold grooves 303 of different molds 3 are not the same, so the shapes and numbers of the force transmission legs 202 of the impact member 2 are also different. The impact member with the corresponding shape of the force transmission leg 202 can be used according to the shape of the mold groove 303 to be disassembled. As Figure 4 shown is a relatively common small impact member. This impact member has four force transmission legs 202 arranged in a square, so that the force is evenly distributed when it is hammered, which is conducive to the disassembly of the mold.

[0038] In use, first retract the inner support base 102 along the track into the outer support base 101. Then, place the mold 3 to be disassembled of the corresponding size on the device. Use the bayonet 104 to hold the gap between the upper mold and the lower mold and push it until it is close. Pull the handle 102c to extend the inner support base 102 along the track. At this time, the bayonets 104 at both ends will support the mold 3. After fully pulling it out, place the impact part 2 into the mold along the mold groove 303. The force transmission leg 202 contacts the lower mold 302. Then, use a hammer or other impact device to strike the force-receiving area 201. After multiple impacts, the lower mold 302 will be forced to fall off, and the disassembly is completed.

[0039] In summary, the rapid disassembly device for small molds of the present invention enables the external impact force to be evenly and centrally distributed to the lower mold of the mold through the design of the support base bayonet and the force transmission leg, thereby reducing damage to the surface of the mold and reducing the risk of mold wear and deformation. When the lower mold falls, it will directly fall into the cavity formed by the two support bases. When using a conventional crowbar and hammer for disassembly, the mold is very likely to fly off at the moment of separation, causing damage to the surrounding environment and even personal safety. Therefore, this structure with a support base cavity greatly improves the stability, reliability and safety of the disassembly process. In addition, through the design of the ball sliding mechanism, the mold can be quickly wrapped for fixed disassembly. The frictional resistance during the sliding of the device is significantly reduced, greatly reducing the time and labor consumed in the traditional method, and improving the work efficiency.

[0040] The above description is only a description of the preferred embodiments of the present invention and does not limit the scope of the present invention in any way. Any changes and modifications made by those of ordinary skill in the field of the present invention based on the above disclosure are within the scope of protection of the claims.
